Animist Intersubjectivity as Argumentation: Western Shoshone and Southern Paiute Arguments Against a Nuclear Waste Site at Yucca Mountain

My focus in this essay is Shoshone and Paiute arguments against the Yucca Mountain site that claim that because Yucca Mountain is a culturally significant sacred place it should not be used to store nuclear waste. Within this set of arguments for the cultural value of Yucca Mountain, I focus on arguments that claim that the proposed nuclear waste site will damage Yucca Mountain and its ecosystem—the mountain, plants, and animals themselves. These arguments assume that Yucca Mountain and its ecosystem are animate and will suffer. An understanding of Western Shoshone and Southern Paiute perspectives on the human relationship to nature, particularly adherence to the concept of animist intersubjectivity, is crucial towards interpreting these arguments. As such, my purpose in this essay is an in-depth analysis of the relationship between the cultural presumption of animist intersubjectivity and Shoshone and Paiute arguments against the Yucca Mountain site. In order to explore this relationship, I begin the paper by discussing concept of animist intersubjectivity as a cultural presumption and its relationship to arguments. Then, I analyze Shoshone and Paiute arguments against the Yucca Mountain site to reveal how animist intersubjectivity influences these arguments. I conclude the essay by explaining the implications of this analysis.     

Brief report: Relationship between performance testing and parent report of attention and executive functioning profiles in children following perinatal arterial ischemic stroke

Children with perinatal arterial ischemic stroke (PAIS) have increased rates of attention and executive functioning (EF) weaknesses. Research in other pediatric disorders has documented poor consistency between parent report of these skills and performance-based measures. We compared these data sources in children with PAIS. Forty full-term (≥37 weeks) children ages 3–16 (median = 7.2 years; 58% male) with PAIS completed neuropsychological testing and composite scores were created for seven attention and EF domains (Processing Speed; Attention; Working Memory; Verbal Retrieval; Inhibitory Control; Flexibility/Shifting; Planning). Parents completed “real-world” functioning questionnaires (ADHD Rating Scale-IV, BRIEF). Correlational analysis were used to compare parent and performance measures. Correlations between ADHD Rating Scale-IV scores and the performance-based Attention and Inhibition composite scores were nonsignificant. Significant negative correlations were found between the BRIEF GEC and performance-based Verbal Retrieval and Processing Speed composites, but remaining GEC/composite comparisons were nonsignificant. Analyses between parent report BRIEF index scores and the corresponding performance-based domain identified one significant negative correlation between the BRIEF Working Memory Index and the Working Memory composite score. While children with PAIS demonstrate difficulties in attention and EF on both parent report and performance measures, little significance was found in comparisons of these two types of measures. There may be several explanations for this dissociation: measures assessing different aspects of the same underlying construct; performance-based measures lacking ecological validity; and parents underestimating/underreporting their child’s deficits. Thus, multiple sources of informant and performance data are necessary to make more accurate conclusions about functioning in these domains.     

Understanding boundary extension: Normalization and extension errors in picture memory among adults and boys with and without Asperger's syndrome

Boundary extension is the tendency for people to “remember” information that fell outside a picture's boundaries. We used a novel test of boundary extension to provide absolute estimates of the magnitude of extension errors and of the degree to which people are influenced by the way a picture is presented at the time of testing. Participants were shown photographs on a computer and subsequently allowed to adjust their magnification to match the size they remembered. The test produced reliable boundary extension of around 11% in adults and large influences of initial test size. In a second experiment we tested boys diagnosed with Asperger's syndrome and matched controls. Both groups demonstrated boundary extension comparable to that observed in adults but greater effects of initial test size. High performance IQ in Asperger's was linked with high levels of boundary extension, while for the matched control group the opposite pattern was obtained.     

Forms of Prosocial Behaviors are Differentially Linked to Social Goals and Peer Status in Adolescents

Traditionally, prosocial behaviors are conceptualized and assessed as a unidimensional construct, but recent research suggests they include various distinct forms, reflecting proactive (instrumental, self-benefiting), reactive (in response to an individual in need), and altruistic (beneficial to others without expectation of personal gain) functions. The authors examined these forms of adolescent prosocial behavior and their links to social goals and social adjustment among peers. In Study 1, they examined agentic (status) and communal (closeness) goals in relation to self-reported altruistic, reactive, and proactive prosocial behaviors. In Study 2, they examined peer-reported altruistic and proactive prosocial behaviors in association with likeability, rejection, and popularity among peers. The associations varied meaningfully among the forms of prosocial behavior. For instance, proactive prosocial behaviors were positively related to agentic goals and popularity, whereas altruistic prosocial behaviors were positively related to communal goals and likeability by peers. The findings underscore the importance of examining multiple forms of prosocial behaviors during adolescence.     

Father Enrollment and Participation in a Parenting Intervention: Personal and Contextual Predictors

Fathers are an important, though often underrepresented, population in family interventions. Notably, the inclusion of ethnic minority fathers is particularly scarce. An understanding of factors that promote and hinder father participation may suggest strategies by which to increase fathers’ presence in studies designed to engage the family unit. The current research examined Mexican origin (MO) fathers’ involvement in a family‐focused intervention study. Participants included 495 fathers from eligible two‐parent MO families with an adolescent child. Individual, familial, and culturally relevant predictors based on father, mother, and/or child report data were collected through pretest interviews and included in two separate logistic regression analyses that predicted the following: (1) father enrollment in the study and (2) father participation in the intervention. Results indicated that higher levels of maternal education and lower levels of economic stress and interparental conflict were associated with increased father enrollment in the study. Rates of father participation in the intervention were higher among families characterized by lower levels of interparental conflict, economic stress, and Spanish language use. Results highlight the relevancy of the familial and environmental context to MO fathers’ research participation decisions. These findings as well as their implications for future research and practice are discussed.     

Social Cohesion and Self-Rated Health: The Moderating Effect of Neighborhood Physical Disorder

Using data from the Los Angeles Family and Neighborhood Survey and its companion datasets, we examined how neighborhood disorder, perceived danger and both individually perceived and contextually measured neighborhood social cohesion are associated with self-rated health. Results indicate that neighborhood disorder is negatively associated with health and the relationship is explained by perceived cohesion and danger, which are both also significant predictors of health. Further, individually perceived cohesion emerges as a more important explanation of self-rated health than neighborhood-level social cohesion. Finally, neighborhood disorder and perceived cohesion interact to influence health, such that cohesion is especially beneficial when residents live in neighborhoods characterized by low to moderate disorder; once disorder is at high levels, cohesion no longer offers protection against poor health. We interpret our findings as they relate to prior research on neighborhoods, psychosocial processes, and health, and discuss their implications for intervention efforts that address disorder in urban communities.     

Natural language processing in an intelligent writing strategy tutoring system

The Writing Pal is an intelligent tutoring system that provides writing strategy training. A large part of its artificial intelligence resides in the natural language processing algorithms to assess essay quality and guide feedback to students. Because writing is often highly nuanced and subjective, the development of these algorithms must consider a broad array of linguistic, rhetorical, and contextual features. This study assesses the potential for computational indices to predict human ratings of essay quality. Past studies have demonstrated that linguistic indices related to lexical diversity, word frequency, and syntactic complexity are significant predictors of human judgments of essay quality but that indices of cohesion are not. The present study extends prior work by including a larger data sample and an expanded set of indices to assess new lexical, syntactic, cohesion, rhetorical, and reading ease indices. Three models were assessed. The model reported by McNamara, Crossley, and McCarthy (Written Communication 27:57-86, 2010) including three indices of lexical diversity, word frequency, and syntactic complexity accounted for only 6 % of the variance in the larger data set. A regression model including the full set of indices examined in prior studies of writing predicted 38 % of the variance in human scores of essay quality with 91 % adjacent accuracy (i.e., within 1 point). A regression model that also included new indices related to rhetoric and cohesion predicted 44 % of the variance with 94 % adjacent accuracy. The new indices increased accuracy but, more importantly, afford the means to provide more meaningful feedback in the context of a writing tutoring system.     

Studying the neural bases of prism adaptation using fMRI: A technical and design challenge

Prism adaptation induces rapid recalibration of visuomotor coordination. The neural mechanisms of prism adaptation have come under scrutiny since the observations that the technique can alleviate hemispatial neglect following stroke, and can alter spatial cognition in healthy controls. Relative to non-imaging behavioral studies, fMRI investigations of prism adaptation face several challenges arising from the confined physical environment of the scanner and the supine position of the participants. Any researcher who wishes to administer prism adaptation in an fMRI environment must adjust their procedures enough to enable the experiment to be performed, but not so much that the behavioral task departs too much from true prism adaptation. Furthermore, the specific temporal dynamics of behavioral components of prism adaptation present additional challenges for measuring their neural correlates. We developed a system for measuring the key features of prism adaptation behavior within an fMRI environment. To validate our configuration, we present behavioral (pointing) and head movement data from 11 right-hemisphere lesioned patients and 17 older controls who underwent sham and real prism adaptation in an MRI scanner. Most participants could adapt to prismatic displacement with minimal head movements, and the procedure was well tolerated. We propose recommendations for fMRI studies of prism adaptation based on the design-specific constraints and our results.     

Children's emotions and coping with interpersonal stress as correlates of social competence

Identifying correlates of children's emotional reactions and coping can provide information about developmental processes and identify useful strategies for improving children's adaptation to stress. We investigated associations of social competence with children's responses to standardised, controllable interpersonal stressors. The stressors included bullying, arguing with a parent, and not being picked for a team sport. We expected greater competence to be associated with certain coping responses, and expected that coping would be better explained by also considering emotional reactions. Children (N = 230, Grades 3 to 7) reacted to three videotaped stressors, and children and parents completed questionnaires. Children rated as more competent used active and challenge coping strategies, such as problem solving and support seeking, more than other children, and they also responded with more sadness. Children's competence was associated with fear, but only in bivariate correlations, and was not associated with angry responses. In a structural equation model, emotions were associated with more coping responses, and the emotional reaction of sadness accounted for the link between children's social competence and adaptive (i.e., challenge) coping. Findings suggest that competent children use more adaptive coping, and this is accounted for by their greater feelings of sadness when dealing with controllable interpersonal stressors.
